ANCHOR.

SPECIFICATION forming part of Letters Patent No. $6,285, dated July 2, 1889.

Application filed November 14, 1888. Serial No. 290,831. (No model-X To all whom it may concern.-

Be it known that 1, JAMES O. JONES, of Mamaroneck, in the county of \Vestchester and State of New York, have invented an Improvement in Anchors, of which the following is a specification.

Anchors have heretofore been made with two, three, or more movable flukes hinged to a head-piece, and in other instances the anchor has been provided with a hollow cone at the end of the stem, the same being usually termed a mushroom anchor.

My present invention is an improvement by which the flukes or arms of the anchor can be held firmly in either an open or a closed condition, and if necessary the flukes can be slipped along upon the shank or entirely removed, so that the conical head can be used in the ordinary manner as a mushroom anchor.

In the drawings, Figure l is an elevation, partially in section, of my improved anchor; and Fig. 2 is a section of the anchor-shank at the line x 00, with three of the flukes extended and the fourth in a folded position.

The shank or stem A of the anchor is of any desired shape or size. The cross-bar B or head will usually be of iron, so as to be unshipped as usual, and at the lower end of the shank A is the hollow conical head or mushroom O, and the lower portion of the shank A is preferably cylindrical for the reception of the collar D. This collar D is made with jaws for the reception of the flukes'or arms E F G H, such flukes or arms terminating in penetrating-points with plates or flukes of any desired size or shape, andthe pins I that secure the respective flukes to the collar D are of a proper strength proportionate to the rest of the anchor. Each fluke is provided with two shoulders orprojections 2 and 3, the shape of the notch between the projections and at the lower end of the arm being such that when the flukes are extended the notch between the shoulders 2 and 3 coincides with the .edge of the hollow conicalhead 0, whereby such flukes are firmly supported by bearing against the edge of such conical head, and when the flukes are folded inwardly the lower ends of the projections 2 rest against the edges of the conical head 0,

by withdrawing the key K, and then the flukes are folded toward the shank and then the collar D is slipped toward the conical head 0, so that the shoulders 2 rest against the edges of the conical head 0, after which the key K is inserted through the mortise in the shank A, and when the anchor is to be used the key K is withdrawn, the collar D moved, and two, three, or more of the flukes swung outwardly, after which the collar D is pressed back to place and the key K inserted for holding the parts in position, and these flukes do not interfere when they are folded with the anchor being used as an ordinary-mushroom-anchor, the hollow conical head 0 embedding itself into the ground in the usual manner, and either one, two, or more flukes may be thrown out as required for use.

I claim as my invention- 1. The anchor-shank A, having a hollow conical head 0, in combination with the .collar D, and the flukes hinged to the collar and resting, when opened, against the edge of the hollow conical head, substantially as set forth.

2. The anchor-shank A, having a hollow conical head 0, in combination with the movable collar D, surrounding and sliding on the shank, the flukes hinged to the collar and each fluke provided with shoulders 2 and 3 to rest against the edge of the conical head when the flukes are extended orfolded, substantially as set forth.

3. The combination, with the anchor-shank A and hollow conical head 0, of the movable collar D, flukes hinged to the collar and provided with the shoulders that rest against the edges of the conical head, and a key K, passing through the mortise in the shank A, substantially as set forth.

Signed by me this 12th day of November, 1888.

JAMES O. JONES.
